Application filed June 10, 189,3. Serial No. l77,219. (No model.)

To a/ZZ whom zit/may concern: j

Be it known that I, JONAS L. KNOLL, a citizen of the United States, residing at Lebanon, in the county of Lebanon, State of Pennsyl-` vania, have inventedl certain new and useful Improvements in Washing Machines, of which the following is a specification, refer-` ence being had therein to the accompanying drawings.

This invention relates to that class of washf ing machines wherein the cleansing of the clothes is eected by means of a vibrating slatted rubber and slatted end racks in the interior of the suds-box and connected to the rubber, to receive therefrom a reciprocating motion to agitate and press the clothes placed between said rubber andracks, to facilitate theremoval of thedirt therefrom, and substantially as shown in Patent No. 406,918, granted to me July 16, 1889. i

The objects of my improvements, are, first, i to improve the construction of the bottom of i the suds-box to render it lighter, stronger and and their inner ends with-wavy-serrated slots to receive their operating pin, and with pe-1 culiarly notched latches to retain each rack-i arm adjustably connected to said operating pin.

will be hereinafter described andspecifically set forth in the claims.

In the accompanying drawings Figure lis a longitudinal vertical section of a washing machine constructedin accordance with my invention. Fig. 2 is a plan view of the same with the cover and the upper part of the han` dles removed, and the side strips of the top turned up on edge to show the grooved 'guides and arm connections for the racks.

Fig. 3 is a transverse vertical section of a portion of the machine through the center thereof. Fig. et is a perspective view of one Fig. 5

Other objects and details of construction of `thebearings for the journals of the rubber, and a portion of the lframe carrying said bearing.` Fig. 6 is a perspective view of lthe inner end of one of the rack-arms of the outer pair, said rack arm having pivoted to its extreme enda latch` havingin its under side notches wider at their upper than at their lower portion, the sides of said notches being in the form of double beveled'spear-heads. Fig. 7 is a perspective view of the inner end of one of the rack-arms of the inner pair. Fig. 8 is a perspective View` of one ofthe latches to engage with the inner pair of rackarms. Fig. 9 is a perspective view of aportion of the outer face of one of the end-frames of the rubber showing the attened or oval stud-pivot thereof and the pivot-pin for the rack-arms. Fig. 10 represents on a large scale `a portionof one of the sides of the suds-box `to its under side `to receive one end of the cover A4, the opposite end thereof resting upon the opposite portion A2 of the top. To the sides ofthe box adjacent to their upper edge, Wood-straps a4 are hinged to permit `them to be swung outwardly when it is desiredto take off all themovable inner parts of the machine to` render the suds-box suitable for rinsingclothes.

The bottom of the suds-box is not made of wood, as said material is objectionable on account of its shrinkage during dry weather, andV undue swelling when the box is filled with hot. suds or water, causing the sides to be pushed apart. In this machine the bot- IOO said zinc and into the bottom edge of said ends and sides. Said bottom edge is preferably slightly beveled outwardly, and to add to the retaining property of the nails and to the liquid retaining capacity of the fastening, the edge of the sheet metal is flanged and forced into the edge of the lumber as at a by means of a suitable calking chisel. To the inner surface of the boX are secured the bearings a7 for the journals or stud-pivots d4 of the rubber D. Said rubber consists of two metallic disks or rings d having a series of slots or pockets on their inner side to receive the ends of the slats d2 extending from one ring to the other. Said rings are united together by means of a bolt d3 in the center thereof. An arm D extends diametrically across the ring from its lower periphery to its upper cross bard and projects upward on top of said cross bar. To the upper ends of said arms are secured the side pieces D2 of the handle D3 said side pieces passing through slots between the cover A4 and the hinged strips a4 of the suds-boX. To permit the rings d to withstand the powerful tractionof the bolt d3 and nut thereon, the portion of the arm D within the ring is provided with an arched rib d5 on each side of the bolt d3, and the cross bar d is also provided with an arched rib. To support the slats d2 against external pressure a substantially cylindrical block d6 is placed in the center of the rubber and each slat is pinned thereto, dividing the interior of the rubber into two equal chambers.

The racks E and E2 operated in connection with the rubber have projecting outwardly from their upper ends pins e by which they are supported; said pins being received in grooved guides F secured to theinner face of the sides of the suds-box adjacent to the top thereof. In the top rib of each of said guides adjacent to the inner end thereof there is a groove f for the passage of the pins e at the v time that the racks and rubb'erare placed` within the suds-box before doing a washing, j

or at the time said parts are removed from the suds-box. The racks E2 have projecting inwardly from their upper ends arms E3, and within the ends of said arms peculiarly shaped slots e3 are formed. The upper edge of each of said slots has wavy serrations to form three (although it mayhave more) shallow pockets e4 eitherone of which is intended to receive in engagement a pin d7 projecting outwardly from the face of the arms D of the frame of the rubber D. To securely retain the pin di' in engagement with either one of the pockets e4, each arm E3 has teeth e5 projecting from its upper edge to obtain seats e6 alongside of said teeth, and with either one of said seats, a latch g is made to engage. Said latch is mounted upon and made to project inwardly from the side of the arm G that has in itsinner end a round hole g2 of slightly larger diameter than the pin 17 in which said pin is received as a pivot for the latch. Said latch has a bent upper lip q3 by which it can be pushed outwardly and lifted by the operator to adjust its position in one of the seats es; but to retain the v latch g normally in engagement with the seatssecar? e6 thelatch is provided with a groove g4 in its side and thereunder, for engagement with a rib e7 on the outer face of the arm E2. The body of the arm E3 having no pivot hole therethrough is not weakened by the removal of any metal from said body.

The racks E have projecting inwardly from their upper ends arms E4, and within the ends of said arms, the peculiarly shaped slots es* are also formed having wavy serrations to form shallow pockets e4* either one of which is intended to receive the pin C17 in engagement. To securely retain said pin Z7 in engagement with either one of the pockets e4 and e4* each arm E4 has pivoted to its extreme end at 7c a latch K having `in its under side notches 7a2 that may be called of dovetail form, being wider in their middle than in their lower portion, the sides of said notches being in the form of pendent double beveled spear head partitions 7a2 that are more reliable than parallel sides to remain in engagement with the pin @Z7 when the parts are wet with slippery soap suds. To prevent the latch K from being swung more than an arc of about one hundred degrees upon its pivot, the end of said latch adjacent to said pivot has a projection 164, to strike against a lug e8 projecting from the side of the arm E4. Said arm has also a lug e2 on the side thereof to keep the latch from being revolved too farin the opposite direction while out of engagement with the pin dl. By having the pivot la for the latch K at the outer end thereof in place of at any point on the arm E4 between theslot e2 and the rack E, said arm E4 is not weakened by the removal of any metal from its body to form the pivot-hole.

To prevent the rubber D or its pivot pins d4 from jumping out of the bearings a7, when the operator gives too great an oscillation to said rubber, or when shipped to uninitiated operators with the side pieces D2 of the handle in a position nearly parallel to the top of the suds-boX, the pins d4 have their sides flattened, and the upper portion or opening as to the bearing a7 is narrower than the interior of said bearing. The width of the openinga,8 is substantially equal to the width of the attened portionvof the pin d4, while the diameter of the interior of the bearing a7 is substantially equal to the vertical diameter of said pin d4. Above the opening 0.2 the sides of the bearing are outwardly iiaring at a2 to permit the operator to easily direct the pins d4 within their bearings, while replacing the rubber D andthe racks E E2 connected thereto, within the suds-box.

To retain the slotted end of the pair of side arms E3 and particularly the slotted end of the pair of side arms E4 of the castings of the racks sprung toward the rubber D, and at the same time retain the ends of the slats h h2 h2 within their pockets in said rack-castings, eachzof lsaid castings has a perforated lug h4 projecting from its inner edge, toward the rubber, and bolts or headed rods h5 are ICO IIO

IZO

received into and retained by said lugs.` The i slats h h2 are wider than those shown in myA Patent No. 406,918, to render them stronger, and are provided on their inner side with a groove h6 having a beveled face and a rectangular edge to properly operate upon the clothes placed between them and the rubber.

By having the rack arms connected to the rubber in a substantially permanent manner, the operator by lifting said rubber out of the suds-box removes also at once the racks from said suds-box, leaving the latter free of incumbrances, to clean it out, adapt it for rinsing clothes, and reduces its weight about one half.

`Having now fully described my invention,

' I claim- 1. In a washing machine the combination of a suds-box, bearings a? centrally secured to the sides of said box and having a top opening to said bearing narrower than its interior, a cylindrical rubber D having slat-retaining cast ends provided with arms D', and

2. The combination of a suds-box, a cylin-` drical rubber pivoted in bearings secured to the sides of said box, the end castings of said rubber having arms D provided with pins 17, two racks having arms, each arm provided With a slot in its inner end adj ustably connected with the pin dl, and a pin e outwardly projecting from its outer end, with grooved guides F receiving the pins e and secured to the sides of the suds-box substantially as described. Y
